The AirTAC GFR300C15JF2TK AirTAC Filter Regulator NPT1/2 is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR300C15JF2TK is an AirTAC GFR300 filter regulator: it removes water and particulate from compressed air and holds a regulated downstream pressure in a single body. This configuration is tapped 1/2 in NPT, carries the standard 40 um filter element, drains condensate by differential pressure, and is fitted with an embedded square gauge reading in psi. A reverse (check) valve is built in, the regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and the unit is supplied without a mounting bracket. The bowl on this size 300 unit is PC (polycarbonate). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and the catalogue options include automatic or manual drains, a 5 um (W) filter element, gauge scales in MPa or bar, G (BSPP) or NPT threads in place of the PT standard, and bracket variants. Flow for the series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeding solenoid valves and pneumatic clamps on a machining centre: the filter element catches compressor moisture and pipe scale before they reach valve seats, while the regulator sets a stable clamp pressure below the header line.
On packaging machines running seal jaws, indexing pushers and case cylinders, the unit keeps carried-over water out of the actuators and holds a repeatable regulated pressure so jaw force and stroke timing stay consistent through the shift.
Mounted at a drop leg serving air tools and fixture clamps in an assembly plant: condensate carried along the main header is drained from the bowl at the point of use, and the outlet pressure is set lower than the main line for the downstream station.
Size and port set the air capacity: this unit is size 300 with a 1/2 in NPT port. Step up to size 400 or 600 where the line needs more flow, or down to size 200 for compact branches - match the size to the air demand rather than the pipe alone. Drain choice matters: the differential-pressure drain on this unit discharges condensate automatically when flow creates enough pressure difference, while automatic (A) drains continuously regardless of flow and manual (M) empties only when pressed. Filter grade is the standard 40 um here; specify W for 5 um where finer protection is needed. The gauge is the embedded square type reading psi; MPa or bar scales and an external round gauge are order options. Thread: PT is the AirTAC standard, and G (BSPP) or NPT (this unit, code T) are specified at order. This configuration is ordered without a bracket (code J); brackets are available as an option. Flow for the series is published as curves, not a single rating, so send us your demand and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowl must not be cleaned with solvents — wipe it with a dry cloth. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your inlet pressure, downstream set pressure and air demand, and we will confirm the flow and sizing from the datasheet before you order.
This unit drains by differential pressure: condensate collected in the bowl is discharged automatically when the flow through the unit creates enough pressure difference, with no button to press, but it relies on air actually flowing. An automatic drain (code A) bleeds continuously regardless of flow, and a manual drain (code M) empties only when pressed. Differential pressure is the standard choice for lines with steady, regular use.
